Abstract:
In this study we report our results on the efficacy of ceftazidime in the treatment of 15 patients with lower respiratory tract infections. Most patients were elderly and had underlying diseases. Eleven patients were cured and one improved. In two cases the treatment was stopped after a few days because of local pain and in one patient a bacteriological failure was noted. Possible side-effects were noted in four cases: skin rash in one, local pain in two and transient rise in liver enzymes in one.
Insights
Ceftazidime effectively treated lower respiratory tract infections in 15 elderly patients with underlying conditions. Most patients experienced positive outcomes, with eleven cured and one improved, demonstrating ceftazidime
Area of Science:
- Infectious Diseases
- Pharmacology
- Internal Medicine
Background:
- Lower respiratory tract infections (LRTIs) pose significant health challenges, particularly in elderly populations with comorbidities.
- Effective antibiotic therapy is crucial for managing LRTIs and preventing complications.
Purpose of the Study:
- To evaluate the clinical efficacy and safety of ceftazidime in treating lower respiratory tract infections.
- To assess treatment outcomes in a cohort of elderly patients with underlying health conditions.
Main Methods:
- A clinical study involving 15 patients diagnosed with lower respiratory tract infections.
- Treatment administered with ceftazidime.
- Patient outcomes, including clinical cure, improvement, and adverse events, were monitored.
Main Results:
- Ceftazidime demonstrated high efficacy, with 11 out of 15 patients cured and one showing improvement.
- Bacteriological failure was observed in one case.
- Adverse events were infrequent, including local pain (2 cases), skin rash (1 case), and transient elevated liver enzymes (1 case).
Conclusions:
- Ceftazidime is an effective treatment option for lower respiratory tract infections in elderly patients with comorbidities.
- The antibiotic was generally well-tolerated, with a low incidence of side effects.
- Further research may explore ceftazidime's role in specific subpopulations with LRTIs.
